YARN-TWISTING DEVICE.

Application filed September Twisting Devices, of which the following is V a speclfication.

This invention relates to devices for twisting yarn.

V Heretoforein machines of this type it has been proposed to use friction caused by a pair of loose rollers respectively resting on a pair of driven rollers and revolved by said driven rollers for drawing the yarn from the creel, the yarn from several spools being combined and passed through a thread guide thence to spools mounted on spindles whereby the combined threads of yarn are given a twist as they are wound on the spools.

It is an object of this invention to eliminate all but one roller and to inject between the roller and the twisting spindle a cylindrical or semi-cylindrical rod which is corrugated, grooved, fluted, or bent at necessary intervals to receive the thread. and around which the thread is drawn, or the rod may be supplied with a plurality of disks or buttons loosely strung on the rod, whereby the. disks when engaged by the thread will readily adjust themselves to a position of alinement for preventing the groups of strands of yarn drawn from the spools of a creel from piling up, one upon the other.

This rod so constructed performs the same function as and replaces all of the rollers which were formerly employed with the single roller now used in the present construction.

A further object of the invention is not only to eliminate a large number of rollers with the consequent elimination of the necessary driving gears and related parts, but to effect a large saving in waste since a break age of thread between a single roller and twisting spindle stops any further pull on the thread being delivered from the spools of the creel.

With these and other objects in view, the invention consists in certain novel. features of the construction, combination and arrangement of parts which will be hereinafter more fully described and particularly pointedout in the appended claims, reference being had to the accompanying draw- 1, 1922. Serial No. 585,734,

ings forming part of this specification, and in which:

Figure 1 is a front elevation of the twist ing machine; I V

Figure 2 is an end elevation of the same, partly in section; and

Figure 3 is an end elevation, showing more in detail the combination of roller and my improved separator. 7

Referring. to the drawings, a preel is shown s'uppl ,ed with a pluralltyof spools 1 mounted in lertical alinement androtatable on sp ndles WhIOlLaYG connected with thebracket 2. Below the alined spools are positively drlven rollers 3which are adapted to receive the threads t which are passed through a thread guide 13 after having beenpassed through a thread guide 5 located between the rollers 3 and the spools 1. Spaced from the rollers 3 and positively driven, are spindles 6 which are adapted to; receive the plurality of threads 4i for twisting said thread and winding them on spools mounted on the spindle.

Locatedbetween. the rollers 3 and the spindles 6 is a separator or spreader 7 which may be a cylindrical or semi-cylindrical rod corrugated, grooved, fluted, or bent at necessary intervals: to receive the threads 4 after the threads'have been looped around the roller 3. V v

In the preferred form of the invention shown more particularly in Figure 1 I have provided a cylindrical rod which has its ends 8 turned upwardly at right angles,

flattened and slotted at 9 to' receive the bolts 10. By use of the slots9 and the bolts 10 which are mounted in the brackets 11 the separator may be moved closer or further away from the rollers 3, the variations in the distance being necessary for use in different kinds of yarns. Loosely strung-on the rods 7 are buttons or disks 12 between which the thread is adapted to be wound on the rods 7 so that the strands of yarn y strands into a single strand 4. As shown in the right-hand side o1 Figure 1 the strands may be looped around the rods 7 and the rollers 3 more than once depending; upon the kind of yarn to be used. A certain amount of. tension is had between the rollers l and the spindles 6 so that when the strands of yarn are drawn over the positively driven rollers 3 and the rods 7, the,

strands will be stretched as they are twisted into a single strand by the spindles 6.

If at any time the strand which is being twisted between the rollers and the spindles should break, the strand will be released from further pull since said strand is not clamped in any manner by the rollers 3 or thelrods 7 and a great saving in waste will be had. I

' Furthermore the usual mechanism for stopping the device when a strand is broken to prevent the strand from being drawn be- 4 tween the rollers is eliminated and thereto-re a great saving in the construction 01 the machinery will be had not only by the elimination or" the numerous rollers and gearing but the safety devices formerly employed between the spindles and the rollers will not be necessary.

I claim: 1. Ina yarn twisting machine, the combination of a positively driven roller, a spindle spaced from the roller for twisting a plurality of threads, and means for'supplylng' a plurality of.threads to be twisted by the spindle, a tensioning rod mounted against rotatlon between the roller and the spindle and provided with spaced means for holdingthe threads in a predetermined position tion of a positively driven roller and a thread receiving rod provided with a plurality of perforated disks mounted on the rod with a plurality of the threads looped around the rod and the roller in groups, the disks being adapted to guide the thread.

4. In a yarn twisting device, the combination of a positively driven roller and a] thread receiving rod, a plurality of disks loosely strung on the rod, means for supplying ap-lurality of threads adapted to be looped around the roller and rod, and a spindle for receiving" a plurality of the threads fortwisting' the same, the disk being adapted to guidethe thread.
